(Note: The actual Residential ESS may also include electrical equipment such as
distribution boxes and metering meters)
Powerporter is a lithium-ion battery pack that can store electrical energy and outputs DC
current. Powerporter only maintains electrical connection with the inverter. The electrical
energy generated by the PV is converted by the inverter Dc to DC and stored in the
connected Powerporter. When Powerporter is needed, Powerporter's electrical energy is
converted by the inverter DC to AC and transmitted to the home grid to provide power for
household appliances.
The main function of the home energy storage system depends on the inverter.
Powerporter is a device that stores electrical energy.
Functions of home ESS:

Self-production and sales of electrical energy
Use solar power and Power Porter to reduce the dependence on the grid and store
electricity during the day for night use.

Backup power
When the power grid is out of power, it can be seamlessly switched to Power Porter as
a backup power source to protect your home from power outages.

Sell electrical energy
The electrical energy generated by the photovoltaic array can be stored in a connected
Powerporter or sold to an energy supply company.
